CALLAHAN prefixes in area code 904
NANPA records 9 assigned NXX blocks to rate center CALLAHAN in area code 904, 1.1% of the 785 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 5 holders hold those blocks, the largest being WINDSTREAM FLORIDA, INC. (3), POWERTEL JACKSONVILLE LICENSES, INC. (2), LEVEL 3 COMMUNICATIONS, LLC - FL (2). The earliest assignment on record here is 2006-03-14 and the most recent 2025-04-18. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
